The San Francisco Giants and the Dave Matthews Band both played Tuesday night — not against each other — in the first big test of whether Mission Bay and South of Market areas can simultaneously handle tens of thousands of people pouring into two major events.

And, it went pretty smoothly.

Maybe that’s because the Giants are drawing only half the capacity crowd these days. Or maybe it was because people took the advice of Chase Center officials and took public transit. Oracle Park has a 41,000-seat capacity while Chase Center has a concert capacity of around 18,000.

“The fact that the Giants aren’t doing so well is making this a lot easier,” said Marlies Zeisler of Marin County who parked on 7th Street and walked to Chase. She was trying to sell an extra Dave Matthews ticket for $140 but it was slow going.

Local residents and businesses were taking a wait-and-see attitude. Even with crowds milling about and with motorists circling the block in search of overpriced parking spots, life went on.

Parking was not only expensive, it was exorbitant. Online, the Giants were offering parking spots for $40 and Chase Center was offering parking spots for $50. At those rates, parking was more expensive than the cheapest tickets to the events that people were parking to see — an upper deck Giants ticket was only $6 and an upper deck Dave Matthews Band ticket was only $30, according to online ticket sites.

A sign directs drivers toward Chase Center as cars slowly creep up 3rd Street looking for parking on a night with the Dave Matthews Band playing the new Warriors arena and Giants toiling at Oracle Park.

The UCSF campus at Mission Bay, only a few steps from Chase Center, said its parking facilities were open only to patients, hospital visitors and staff. A campus spokeswoman said guards and monitors had been assigned to monitor the $4-an-hour lots to make sure no Chase customers were parking there.

Signs in front of the UCSF lots proclaimed “no event parking.” That could change in the future, the UCSF spokeswoman said, if the medical center determines that its lots can accommodate some Chase customers.

Muni was offering a free deal only to Chase Center customers, who got free rides all day by showing their tickets to Muni operators and station agents. Giants fans had no such luck.

Still, a Muni train to Mission Bay was mostly empty.

“They said it would be crowded,” said Ray Dolby of Toronto who was headed to the Giants game with his wife. “It’s not crowded. We’re lost. We don’t know where the hell we’re going. So we’re glad it’s not crowded.”

Lots of people were walking from the Embarcadero toward the ballpark and Chase Center.

The Muni deal is part of the Golden State Warriors’ arrangement with Muni to reimburse the transit agency for its customers’ fares, based on a transit study to be conducted in coming days and weeks.

“It’s something the Warriors are eventually going to be paying us back for,” Muni spokesman Erika Kato said.
